GEARING FOR STENTERING OR OTHER MACHINES.

SPECIFICATION formingpart of Letters Patent No. 714,078, dated November18, 1902. Application filed May 16, 1902. Serial No. 107,628. (Nomodel.)

To all whom, it may concern:

Be it known that I, ALFRED AUSTIN WHIT- LEY, engineer, a subject of theKing of Great Britain and Ireland, residing at 2 Malvern Villas, Oheshamroad, Bury, in the county of Lancaster, England, have invented certainnew and useful Improvements in Gearing for Stentering or other Machines;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention has for its object to provide stentering-machines with asimple and efficient gear by means of which the fabric passing throughthe said machines can be straightened by giving a variation of speedbetween the chain-wheels by which the chains carrying the clips whichclip each side of the fabric are driven, the arrangement being such thatthe gear occupies but a small space and is powerful and durable.

Figure 1 represents in vertical section, and Fig. 2 in horizontalsection on the line 2 2, Fig. 1, an arrangement of gearing according tomy invention.

A is the chain-wheel whose speed is to be regulated, the saidchain-wheel being fixed to a sleeve G, mounted loosely on the shaft B,on which shaft B is keyed a spur-pinion O, in gear with two spur-wheelsD, mounted to rotate around spindles D, secured in a casing E, which iscapable of rotating on the shaft B. The part of the sleeve F which is inthe casing E is formed with or has fixed to it a pinion G, which throughintermediate toothed wheels H, mounted to rotate on studs H, carried bythe casing E, is geared to the spur-wheels I, each connected with one ofthe aforesaid wheels D, so that the wheels D and I of each pair rotatetogether. The casing E has secured to it a worm-wheel K,with which gearsa worm L on a shaft capable of being rotated from any convenient part orparts of the stentering-machine. So long as the casingE is stationary(as it is under normal conditions) the chain-wheel A will be driven fromthe chain-wheel-driving shaft Eat the same speed as that shaft B throughthe medium of the gear-wheels O, D, I, H, and G within the stationarycasing. If,

however, rotary motion in one direction or the other be imparted to thecasing E (by means of the worm L and worm-Wheel K) while thedriving-shaft B is rotating, the gearing within the casing will act moreor less as a planetary gear, and consequently the normal speed at whichthe Wheel A is driven from the shaft B will be retarded or accelerated,according to the speed at which and the direction in which the casing Eis being turned.

If desired, the teeth of the pinions C and G can be made broad enough toallow the surrounding wheels to be placed on difierent levels, so as towork on different parts of the teeth of the said pinions G and G.

Having now particularly described and ascertained the nature of the saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is In a stentering-machine, means for imparting variablemotion to the chains of clips, by which the edges of the fabric areheld; the said means consisting of the combination with the chain-wheel,around which one of the chains of clips passes, of a chain-wheel-drivingshaft having a spur-pinion fast thereon, a spurpinion fast with thechain-wheel, the said chain-wheel and its pinion being mounted looselyon the chain-wheel shaft, a casing mounted loosely on the said shaft,studs in the casing each carrying a pair of spur-wheels connectedtogether and mounted loosely on the said studs, one of each of the saidpairs of spur-wheels gearing with the aforesaid spur-pinion fast on thechain-wheel shaft and the other spur-wheel of each pair gearing withintermediate toothed wheels mounted on two other studs in the casing andgearing with the aforesaid spur-pinion mounted loosely on thechain-wheel shaft and means for rotating the casing in either directionso as to vary the speed of rotation of the chain-wheel substantially ashereinbefore described.

In testimony whereof I affix my signature in presence of two witnesses.

ALFRED AUSTIN WHITLEY.
